ADJUSTING DEVICE FOR BUTTlNG-BOARDS.

SPECIFICATION forming part of Letters Patent No. 554,726, dated February 18, 1896. Application filed April 22, 1895. Serial No. 546,675. (No model.)

To all whom it may concern.-

Be it known that I, JOHN IV. PRIDMORE, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain newand useful Improvements in Adjusting Devices for Butting- Boards, of which the following is a specification.

It has been found necessary for many years to assist the butts of the grain in their onward path to the binder by means of different forms of actuating devices. These actuating devices, usually called butting-boards, have been usually "pivoted at the receiving end and left to swing freely at the discharge end, and controlled by a handle extended convenient to the driver. It has also been found necessary to adjust the binding attachment for central binding inasmuch as the butting-board has not had sufficient sweep to change the path of the stream of grain, varying as it does in length, so that the band will be placed centrally about it. The driver has thus had two levers to work whenever the length of the straw has varied greatly.

My improvement relates to the particular means of adjusting the binder and the butting-board by one movement.

In the drawings, Figure 1 is an end view of so much of the harvesting-machine and binding attachment, with the butting-board in position, as is necessary to show my invention; and Fig. 2 is a plan View showing the particular arrangement of the connecting devices that I use.

In the drawings, A represents the main wheel of the harvester 5 B, the main frame; C, the binding attachment adjustable along the delivery end of the harvester by any of the various well-known means of lever and crank attachment; D, the butting-boarchits receiving end actuated by the crank d and its delivery end supported by the elbow-arm (1, extending from the top of the elevator.

As thus far described, the construction is old in self-binding harvesters.

It will be noticed that the binder must be adjusted in one direction, while the buttingboard must be moved inthe opposite direction in order to place the band centrally about varying lengths of grain, and in order to do this with the same movement of the binder I pivot an arm E on a fixed part of the harvester-as, for instance, on the top of the defl ecting-board F. This part is stationary upon the machine. I connect the adjuster with the extremity of the arm E by means of the link G. The adjuster is thus connected to the harvester by means of a broken or jointed link connection. From the joint of the links, or closely thereto, I extend a 0011- necting-rod H and attach it to the spring-rail I of the binder. This spring-rail is rigidly fastened to the binder-frame C and moves with it when the binder is adjusted.

It will be seen from the construction described and from the drawings that the movement of the binder will break the joint and shorten the connection of the link-straps E and G, and thus throw the board rearwardly when the binder is adjusted forwardly, and vice versa.

I am aware that other forms of connecting devices have been made to insure the movement of the adjuster from the binder, but

none have been so simple nor have they given the ratio of movement between the binder and the adjuster in as good proportions, nor have they been as firm and free from rattling, as the construction here shown.

Having now described my invention, what I claim is 1. In combination in a self-binding harvester, a movable binder adjustable along the delivery end of the harvester, an adjuster located at the butts of the stream of grain and pivoted to the harvester at its receiving end, a connection from the delivery end of the board to the harvester formed by two links, and a link connecting the binder to the connection that joins the adjuster and the harvester, whereby the adjustment of the binder throws the link connection between the harvester and adjuster to and from a straight line.

2. In combination in a self -binding harvester, an adjuster pivoted at its receiving end to the harvester and supported at its delivery end by a link extending from the ha-rjusted for long and short grain the broken vester-frmne, a binder adjustable along the link will be brought to and thrown out of a harvester, a broken link connecting the harstraight line, thus moving" the butting-board. 1o
